Title: Gas fuelled lighter
IPC: F23Q2/16
Filed: 1969-03-26
Abstract: 1,217,643. Gas fuelled lighters. SOC. FRANCO-HISFANO-AMERICAINE FRANCISPAM. 26 March, 1969 [29 March, 1968], No. 15698/69. Heading F4F. The flint-spring supporting screw 36 of a gasfuelled lighter performs the additional functions of retaining a base-plate 3 in position and regulating the flame height by adjustment of the vertical position of a removable reservoir 6 relative to the body 1 of the lighter. A portion 8b of a valve 8 (Fig. 5), carried by the reservoir abuts a shoulder 45d in the body, and is moved relative to a portion 8a of the valve, as the reservoir moves, changing the degree of compression of a porous washer 48 through which the gas flows. The screw 36 (Fig. 3) is engaged in a flint tube 32 passing through the reservoir 6, and a collar 39 moves the reservoir accordingly. A spring washer 41 beneath the screw head retains the base-plate 3 in position. On lifting the lighter cap 2, links 18, 21 following slots 22, 23 operate a pivoted forked lever 12 to release gas from the valve 8. Simultaneously, by means of a toothed sector 24 and gear 26, a flint-wheel 28 is moved to a protruding position where a spark may be produced by thumb movement.

Title: Method of and apparatus for manufacturing belting and the like
IPC: B32B27/00
Filed: 1950-06-27
Abstract: 683,778. Compound sheet materials; coating webs. SERRA, J. DUARRY-. June 27, 1950. [July 1, 1949] No. 16057/50. Class 140. Laminated belting or the like is made by separately impregnating a number of bands of woven fabric with an aqueous dispersion of rubber, gutta percha, balata, or synthetic rubber, combining the impregnated bands into a single belt, and piercing the belt by means of a plurality of piercing members, which, after having pierced the belt enter into a further quantity of the rubber or like dispersion and on withdrawal, pick up threads of dispersion and draw them through the belt. The impregnated bands may be treated with carbon dioxide before being combined to form a belt, and the latex mixture may contain hexamethylenetetramine. As shown, bands 1, Fig. 1, of woven fabric are drawn from rolls .2 through tanks 3 containing latex, past distributers 6 which supply carbon dioxide from a container 5, and are united into a belt between a scraper 7 and roller 8. The belt, before passing over a table 10, is subjected to the action of punches or spikes 11 carried by a rotating roller or, as shown, mounted for vertical reciprocation by a crank 12. The punches or spikes perforate the belt and enter into rubber latex in a trough 13. On withdrawal of the spikes latex is drawn through the perforations in the form of threads, any surplus latex wiped off from the spikes falling back into the trough. The belt then passes under a scraper 14, and over a heated table 15 which dries the lower surface of the belt while its upper surface is dried by infra red lamps 16. The belt is additionally acted on by pairs of squeeze rolls 20 and 21, and, if desired, by air from a compressor 19 and carbon dioxide from a container 18. Further treatment of the belt includes passage over rollers 22 to 25 heated to successively increasing temperatures, over a guide roll 30, and between pairs of rolls 31 and 32 of which rolls 32 are driven faster, before being wound on a drum 35. The fabric-treating tanks 3 each have a guide roller 40, Fig. 3, at the inlet end, a guide 48 under which the fabric passes to ensure immersion, and a bent-over portion 41 at the exit end which co-operates with an adjustable scraper 4. Specifications 426,988 and 548,409 are referred to.

Title: A method of joining pieces of veneer and of wood of any thickness in the direction of the grain
IPC: B27F1/16
Filed: 1928-06-05
Abstract: 291,794. Wegner, L. M. Cohn-. June 10, 1927, [Convention date]. Joints, carpenters' &c. - Thin wood such as veneers, plywood, and the like is joined in the direction of the grain by forming interfitting portions on the ends to be joined which extend partly in the direction of the grain and partly at an angle thereto, and subsequently glueing the joint. The wooden strips a are disposed in packs on the table of a milling machine and rest against a stop-piece c on the table, and the ends are milled out to the shape shown at b by a single cutter or a multiple built-up cutter d. The pack comprising the parts to be joined to those already cut is then cut but is displaced laterally the distance of half a tooth by a packing-piece e, so that after cutting and reversal, the ends can interlock with those on the first pack. The ends of the pieces a<1>, a<2> are then glued and pressed together. The glueing may be performed by a rotary glue brush while the pack is still held on the table after cutting.

Title: Improvements in or relating to relative phase responsive arrangements
Inventor: RUST NOEL MEYER
IPC: H03D13/00
Filed: 1951-07-10
Abstract: 703,189. Phase-difference measurements. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 20, 1952 [July 10, 1951], No. 16358/ 51. Class 37 A phase responsive arrangement comprises means for producing, from each of the waves to be compared, one pulse per cycle at a predetermined point in the cycle, a multi-vibrator circuit, means controlled by the produced pulses for controlling the operation of this circuit between its two conditions of stability, in dependence upon the phase relation between the pulses from the two waves, and means for charging a condenser at a predetermined rate in one direction or the other according to the condition of stability of the circuit. The, two waves to be compared are fed at A1, B1 to two separate channels A,' B and amplified by amplifiers A2, B2, the amplifier A2 being followed by a phase changer A3, squaring circuit A4, and differentiating circuit A5. The amplifier B2 is followed by a squaring circuit B4, and differentiating circuit B5. The outputs of the circuits A5, B5 are fed to selector circuits A6, B6 which select only the pulses of the same predetermined polarity, which are fed to the grids of the valves VA, VB of a multi-vibrator circuit having two conditions of stability, in one of which only the valve VA conducts and in the other of which only the valve VB conducts. Each pulse occurs when the wave passes through zero in 'one chosen direction only. If the pulses from channel B. occur midway between those from channel A the periods during which the two conditions of stability exist will be equal, but for all other relative phases between the inputs A1, B1 these periods will be unequal. Connected between the anode circuits of the valves VA, VB is a condenser CAB, which is charged in one direction or the other according to whether VA or VB is conductive. The voltage across this condenser represents by its sign and magnitude the phase relation between the inputs to A1, B1 and may be applied to actuate a voltmeter or to produce a control action. Condensers 1C, 2C may be connected in the anodegrid cross connections between the valves VA, VB to make the circuit frequency-selective so that a multi-vibrator action occurs wherein. the conduction changes of the valves become automatic at a desired frequency.
